What Cardinal does
Hey YC! We're Devi and Jianna - the founders of Cardinal. TL;DR: Cardinal is the AI platform for precision outbound. We run outbound for 40+ YC companies, like Mintlify, Greptile, and Luminai. The Problem “Spray and Pray” outbound is dead. The best teams at outbound do it with extreme precision. Finding things in common with your customers, staying in touch with them through their content, mapping inbound from signups and ads, tracking website visitors, monitoring various signals, etc. This sounds great in theory, but in reality involves stringing together 10+ tools and hiring a GTM engineer. That’s where Cardinal comes in. Cardinal is an AI platform for precision outbound. Our agents can create workflows that normally require the work of fulltime GTM engineers. If you're a founder or sales leader looking to bring AI into your sales org, would love to chat!
